Also, I just had this idea. I don't know if it's worth it, and this pretty greedy and might take too long to work, but for Pokémon that aren't good against Leavanny:

Get someone trustworthy to TM-teach it False Swipe, get it to relearn Fell Stinger, and then how it works is against opponents that aren't good against Leavanny, (first Attack EV train) use False Swipe, and with the Attack EV training, Leavanny wil have a powerful False Swipe. Hopefully my plan is it takes the target down to 1HP, then I use Fell Stinger to KO the opponent and raise Leavanny's Attack.

If it works, I probably shouldn't try it too much, because Leavanny, well, is ultra-weak to Charizard (normal and Y, not X) and Charizard is common in Battle Colosseum, so well uh yeah
